Java POJO without getter/setter equals/hashcode
Simple way to generate getter/setter, equals/hashcode and default constructor without ever having to own that code.
@RequiredArgsConstructor
@ToString
@EqualsAndHashCode
public class Animal {
@Getter @Setter private String name;
@Getter @Setter private String gender;
@Getter @Setter private String species;
}
Check out (Lombok)[http://projectlombok.org/] when you have time.
Oh and heres the above code without Lombok:
public class Animal {
private String name;
private String gender;
private String species;
public Animal(String name, String gender, String species) {
this.name = name;
this.gender = gender;
this.species = species;
}
public String getName(){
return this.name;
}
public void setName(String name){
this.name = name;
}
public String getGender(){
return this.gender;
}
public void setGender(String gender){
this.gender = gender;
}
public String getSpecies(){
return this.species;
}
public void setSpecies(String species){
this.species = species;
}
@Override
public boolean equals(Object o) {
if (this == o) return true;
if (!(o instanceof Animal)) return false;
Animal animal = (Animal) o;
if (gender != null ? !gender.equals(animal.gender) : animal.gender != null) return false;
if (name != null ? !name.equals(animal.name) : animal.name != null) return false;
if (species != null ? !species.equals(animal.species) : animal.species != null) return false;
return true;
}
@Override
public int hashCode() {
int result = name != null ? name.hashCode() : 0;
result = 31 * result + (gender != null ? gender.hashCode() : 0);
result = 31 * result + (species != null ? species.hashCode() : 0);
return result;
}
@Override
public String toString() {
return Objects.toStringHelper(this) //Using guava library objects toString
.add("name", name)
.add("gender", gender)
.add("species", species)
.toString();
}
}
